My main worry with guidelines like these—particularly #2 and #3—is that Tom will see them as "just another set of rules" that people can game and lawyer their way around.
I actually like them.
I would merge them into one, because they are pretty much the same, and I would remove the realm limit:
Don't post stuff to the forum that is not already public knowledge in-game.
Maybe with a footnote that explains that "public knowledge" doesn't mean every single character has received a message with this info, but that every character COULD HAVE learnt about it. You know, it's not a secret, it's not a private discussion, it's not a current local thing. It could've spread around by the time you post it to the forum.
